Guinea-Bissau Sign Language is an incipient sign language evolving from the single school for the deaf in Guinea-Bissau, which was founded in Bissau in 2003. In 2005 a linguist and Portuguese Sign Language teacher found GBSL to still be basic, but with some consistency among students in the school and village use when the students went home.
